Learn the basics of Ruby with hands-on practice.

Become a Ruby Professional

Do you want to be an interpreted language geek? Are you tired of getting entangled in the dense syntaxes? Does it irritate you to compile your code to machine language first? Are you looking for an easy-to-use scripting language? Well, Ruby is the best pick for you then!
This introductory module will be providing you with hands-on practice with the support of a bunch of interactive illustrations, exercises, and the integral topics of variables, built-in classes, objects, conditionals, blocks, and much more!

Learn Ruby from Scratch

## Problem 

You’re given an input text that contains some data (alphabetical characters only). This data appears between two different types of tags. It appears between either the `class` tags or the `object` tags as shown:

1. `<class>`Something`</class>`<p>

2. `<object>`SomeOtherThing`</object>`
 
Your task is to use a regular expression to extract the data enclosed within the `class` tags.

### Example
Consider the input below:

```HTML
<class>Hash</class> <object>true</object> <object>nil</object> <class>TrueClass</class>
```

The output should be:

```ruby
[["Hash"],["TrueClass"]]
```
